iRONDO J'. BLACKBURN, OE BULLS GLAP, TENNESSE13.

CAR- 13003,

Application filed March v12, 19.15.

1 '0 all whom it may concern Be itjknown that LRONDO J. BLACKBURN, acitizen .of the United States, residing at Bulls Gap, in the county ofHawkins and State of Tennessee, .have invented certain new and usefulImprovements in Car-Door Fasteners, of whichthe following is aspecification.

While the invention is intended most especially toprovide novellockingmeans for car doors, the samemay be applied with equal advantage tosliding doors of-any type.

The main reason for adaptingthe fastening mean most especially tocardoors is the feature wherebv the door is moved laterallv and drawnclose .againstthe side of the car, thereby preventing the formation ofany crack or space which would admit of the waste of grain, plaster orother similar commodity stored in the car for transportation.

A further purpose of the invention .is the provision ofsimple-andeifective fastening means which be readily operated andwhich-may be-adjusted so as toprevent any part projecting so asto be inthe way or liable to cause injury by striking an object.

dVith these and other objects in View, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly claimed.

In the accompanying drawings has been illustrated a simple and preferred.form of the invention, itbeing, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention as claimed maybe resorted to when desired.

the pivotal connection between the operating lever and shaft.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral-1 designates the side of {lrbOX car which is provided withan opening adapted to be closed by means of a sliding door 2 mounted torun upon an overhead track 3 and provided with hangers l to travel uponsuch track. The lower end of thedoor is retained in proper position bymeans of a guide 5 which is secured to the car below thedoor openingandengages the lower portion of .the door so as to retain it intheproperposition. A stop 6 is located at one side of thedoor opening to limitthe closing of the door. A bracket stop 7 isdisposed upon the side ofthe car some distance from the door openingto limit the movement of thedoor when slid into open position.

A shaft 8 is arranged upon the outer side of thedoor andextendslengthwisethereof and is provided at opposite ends with arms 9, whichcurve throughout their length and terminate in projections 10. The arms9 are disposedat a right angle to the length of the shaft 8 and projectthrough openings 11 formed in the door 2 nearopposite vertical edgeportions thereof. A recess 12 is in communication with the inner end ofeach opening 11 and is disposed above such opening formed in the inneror rear side of the door. Lhe recesses l2 are of a length and depth toreceive the projections 10 of the locking arms 9 when the latter arewithdrawn to a positionto release the door and admit ofthe same beingslid either into open orclosed position. Apin 13 intersects each oftheppenings 11 and sustains the wear incidenttothe movementsof thelocking arms as [well as assisting materially in securing the door.Openings 17 17 are formed in the side .of thecar adjacent the dooropening and are adapted to registerwiththe openings 1 1 when the doorisin closed position was to receivethe locking-arms 9 when projecteddntolockingenga gement with the car. A pin 1'5 intersects each of the openins 14 andenga-ges thecurved end of the locking arm 9 when projectedthrough theopening Strips lfiare attached totlie-inner wall of the sideof the car, ,and receive. and house the inner'ends ofthe locking arms 9'wlien ar sette rat rnieaedeietp sesaseeiee with the ear to secure thedoor. lVhen the door is locked the outer ends of the locking arms 9extend across the pins 15, as shown most clearly in Fig. 3, therebydrawing the door 2 close against the side of the car and preventing anypossible outward movement of the door. It is also noted that the arms 9extend across the openings 11 and 14 and thereby prevent slidingmovement of the door into open position. The shaft 8 is mounted so as toreceive a two-fold movement, the one being slid able vertically alongthe outer side of the door 2 and the other pivctal to admit ofwithdrawing and pro jeeting the locking arms. These two movements aresimultaneous and are essential to the proper operation of the lockingarms.

Keepers 17 are located upon the outer side of the door near the verticaledges thereof and receive opposite end portions of the shaft 8. Thesekeepers retain the shaft in proper position and direct it in itsvertical sliding movements. An operating lever 18 is pivotally connectedto the shaft 8 and is formed at its pivotal end with furcate portionsbetween which a lug '19 is received, a pivot 20 passing through registering openings in the overlapping parts and serving to pivotallyconnect the lever 18 to the lug. The operating lever 18 is formed nearits free end with a slot through which passes a latch member 21pivotally connected to a bracket 22 which is secured to the door 2 abovethe pivot fastening of the lever 18 with the shaft 8. The latch member21 is substantially of L-shape and one member is adapted to extend alongside an ear 23 projecting outwardly from thebracket 22, both parts beingapertured to receive a seal 24 to secure the operating lever in lockedposition.

A sliding door provided with locking means embodying the invention isadapted to be drawn close against the part in which thedoor opening isformed and is at the same time adapted to be secured against beingopened. Vhen the door is closed the shaft 8 is moved upward and at thesame time turned, thereby projecting the locking arms 9 through theopenings 11 and 14 and engaging the pins 13 and 15, such operating leverbeing secured bv the latch member hereinbefore stated. Nhen the door isreleased the shaft 8 occupies a position at the lower ends of thekeepers 17, as indicated most clearly in Fig. -5 and the operating lever18 is-turned so as to lie close against the shaft and side of the doorso as not to be in the way.

Having thus described the invention, what is'claimedas new is 1. Afastener comprising a shaft mounted to receive both a pivotal and alateral sliding movement and provided with an off standing locking armwhich is projected or withdrawn by the combined pivotal and slidingmovements of the shaft.

2. A fastener comprising a shaft mounted to receive a pivotal andlateral sliding movement and provided with a curved locking armprojecting therefrom substantially at a right angle, and a keeper forengaging the shaft and retaining it in proper position d ring itspivotal and lateral sliding movements.

3. In combination with a part having an opening and a sliding door forclosing such opening, a shaft mounted upon the door and adapted toreceive a combined pivotal and sliding movement. locking arms projectingfrom the extremities of the shaft and forming a part thereof and adaptedto pass through the door and engage the part in which the door openingis formed, such locking arms being curved throughout their length andadapted to draw the door toward the part in which the door opening isformed.

4. A door fastener comprising a shaft mounted to receive a combinedpivotal and lateral sliding movement and formed with offstanding lockingarms which curve throughout their length and terminate with projectionsformin stops, said locking arms being disposed to operate throughlateral openings formed in the part upon which the shaft is mounted andsuch lateral openings having recesses in communication therewith toreceive the projections of the locking arms.

5. In combination with a part having a door opening and formed at thesides of the door opening with lateral openings. pins disposed in suchlateral openings, a sliding door having lateral openings to registerwith the lateral openings of the part in which the door opening isformed and having recesses upon its inner side in communication with theends of the lateral openings, pins located in the lateral openings ofthe door, and a shaft slidably and pivctally mounted upon the door,curved locking arms projecting from the shaft and adapted to operatethrough the lateral openings of the door and the part in which the dooropening is formed and engage the pins arranged in both lateral openings.and stop projections at the ends of the locking arms to enter therecesses in communication with the lateral openings of the door.

In testimony whereof I afiix my signature in presence of two witnesses.
